About This Test
HBV is a viral infection that has a profound liver impact. This test assesses hepatitis B surface antibody (anti-HBs) levels in blood, revealing immunity status. A positive result denotes immunity from vaccination or prior infection, while a negative result indicates no Hepatitis B antibodies or established immunity. This information is crucial for understanding one's susceptibility to the virus and their potential need for preventive measures.
Who Should Have This Test
This test is for anyone who wants to determine previous infection or immunity to HBV. You must be 18 years old or older to order.
How This Test is Performed
